Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.13.8

Description The issue is related to the usb serial console disconnect function in the Linux kernel, which can cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device. This is related to disconnection and failed setup. The vulnerability allows local users to exploit the issue, potentially leading to a system crash or other unspecified effects.
